Abstract
The invention concerns a lead-through means for cables or pipes comprising an outer frame (11) and having at least one sealing module (1) arranged inside the frame and which at least one module surrounds a cable or a pipe (8). The sealing module (1) is divided in its longitudinal direction and is built up with peelable sheets (3) for adaptation of its duct area to the actual cable or pipe (8) and which sealing module (1) is intended to fill out the opening of the frame (11) together with at least one expansion unit (12). The sealing module (1) has a dividing cut (2′) for division into two halves which cut runs obliquely in relation to the longitudinal direction of the sealing module (1) or the longitudinal axis (5) of its duct (4), whereby at an adaptation of the sealing module (1) to the actual cable or pipe (8) one module half (1′) may be turned 180° during a first stage to achieve a conical duct through the sealing module (1) at the same time as an oblique gap (6) is formed between the module halves (1′, 20 1″). The module (1) may there after be adapted to the actual cable or pipe (8) until the module halves (1, 1″) reach each other at the narrow end (6′) of the gap (6) and whic…
